invented certain new and useful Improvements in Preparations ofIngredients for the Production of Colored Calcimine's, of

which the following is a specificatiom My invention relates to coloredcalcimines,

and has for its object to prepare and procolors), but some of them alsoas to amount,

serve the ingredients of colored calcimines in such a Way that they willnot deteriorate as readily as the usual colored calclmines, and alsowith a view of reducing the stock which a jobber, dealer, or decoratorwill have to keep on hand in order to meet the demand for differentcolors (hues) or tints. According to my invention, the ingredients ofthe colored calc'imine are prepared in two separate masses of measuredamounts, j or units, to wit, a body substanceformed or put up inmeasured quantities or body units, and a number of coloring substancesalso in measured quantities or color units. While all body unitsprepared according to my invention are supposed to be alike both incomposition and in amount,

the color units would differ not only as to their composition (so as toproduce different so as to produce different tints of the same color.This feature of'having color units of different amounts for'theproduction of different tints of the same color, is however notessential to all forms of my present invention. Preferably, the bodyunits as well as thecolor units are made 1n dry (solid) form, asdistinguished-from liquid or semiliquid (paste-like) ingredients, and inpar-v ticular, there are certain advantages to be obtained, as morefully set forthhereinafter, by employing the solid units, andparticularly the color units, in coherent form, such as blocks ortablets. In any event, the use of my invention will enable various tints and colors of great uniformity to be pro duced readily, withoutrequiring any speol al' skill. I also generally provide a chart shbwling the various tints and hues which will'be obtained byusing my bodyunits in con-' junction with various color units.

In detail, I may proceedas follows: a calciinine body, I may use anysuitable calcimine body which ,is'white or nearly"so, many of themixtures now on the market Patented Nov. 2o, ism. Appllcatiomfiled March"27, 1914, Serial Nb. 827,613. Renewed October 1, 191a. seriaino. j

I may niention the' ealci mine bodyproduced according toMoores United States Letters Patent No. 488,02d asan example of the many compositions suitable for use as a calcimine'bOdy in 'my'invention, it'being understood that myp'resent i compositionof the calcimine body.

or other suitable containers, preferably dry,

say in amounts of 1000 grams each, and

these measured quantities of ca'lcimine body Iterm thebody units.-

Furthermore lf'provide, preferably" also as dry'solid material, colorunits of asuitable'f character." All materials of the calcimine shouldbe ground to "a very fine state of subdivision, but my" invention isnotrestrict'ed" ,to the use of any particular'coloring materials. Asexamples. of coloring'materials suitable for the purposes of myinvention, I Wlll men tion ultramarine for blue, lead chromate foryellow, .andbrimson lake for red; these three colors maybesuilicienttoproduce all the tints and hues -desired. I

may use other pigments, suchna's chrome green, carbon 'blackfetc but, asstated above, the exact nature of the colorin'g"material isnot-th'esubject of my present invention. Whatever be the nature of the coloringmaterial used, each is separated into color units of definite a'mq unt(wei"ght) and coloring strength. These 'colo r might be put up inftheform of coherent" bodies, as solid blocks or tablets, compressed in"tableflmolding machines of any ap-f.

proved character, and these color -units, when in coherent masses, mightbe kept to f gether in the same container even though such units diiier;in color, or the coherent color units might even be kept without-anycontainer. If the color units are not coher out, say if they are kept aspowders, suitable containers, as bags, envelope, cans, or capsules wouldbe required for the indiice its

vidual color units. In any event, the color units would be of uniformand accurately measured quantities, which would always be much smallerthan those of the body units.

4. For instance, to. produce the lightest shade of blue in connectionwith one of thebody units, I might have blue (say, ultramarine) have'aspecial color unit.

color units of one the next shade of b no, I might haveblue ram each; toproduce color units of two grams each, and so on. For each-tint or hueto be produced, I would Color units of "like, constitution, but ofdifferent wei ht or 2 amount, would be employed for pro ucing. differenttints oi the same hue or color, while for producing different colors, Iwould employ color units of difi'erent'mavjterials or at least differingin the propor- '-lt,ions.ofthe materials, in the case of color unitscontaining two or more-coloring -ma- 'terials. a i

With the units described above, I would supply' a chart showin the exacttints and huesor'colbrs obtaina lebyusmg each of the particular colorunits in conjunction units. The chart Por- Themethod of using the newcalcimine kilogram of dry' calcimine is usually suflicient. If thecalcimine body units are of 1 kilogram each, the workman will take withhim one of the calcimine body units and an assortment of-color units,Since the latter are of high coloring power, they will be very smalcarry with him a large assortment of color units, or even a completeassortment. From the chart brought by the workman, the customer wouldselect the desired tint or color, and the workman would then read ofifrom the chart, the exact formula of such tint or color,'that is to sathe kind of color unit to be employed. T e color unit might bedisintegrated first in water,'and then mixed with the body unit; or thebody unit might be mixed first with slightly less than the requiredquantity of wateigand thoroughly distributed therein, the color unitbeing similarly mixed with water and distributed therein whereupon thetwo liquids would be poured together and stirred. .The total amount ofwater might be,say 11} liters to each-kilogram er calcimine.

The use of the units in dry,solid form further minimizes or eliminates entirely, the danger ofnoxious interaction between the material of the container and theingredients of the body units These advanor color units; besides, solidunits can be I kept in paper bags or other chea containers which wouldbe quite unsuitaldle withingreiiients of a liquid or moist nature.Furthermore, if the color units are made in the form of tablets or othercoherent masses, it will not be necessary to provide a separatecontainer for each color unit, since color units of different kindsmight then be kept in the samecontainer, 01' the coherent color units,particularly in the form of compressed tablets, might be kept withoutany container whatever.

From the above explanations it will be understood that my inventionoffers very important advantages as regards the preserving of thecalcimine ingredients, the prep.- aration of the calc'imine "for use,the percellent results may be obtained at a reduced cost, withoutrequiring any unusual skill.-
